|Color||A color expression that indicates the background color of selected nodes. Use the Add method to add new skins to the control. If you need to remove the skin appearance from a part of the control you need to reset the last 7 bits in the high significant byte of the color being applied to the background's part.|
The following VB sample changes the visual appearance for the selected node. The SelBackColor property indicates the selection background color. Shortly, we need to add a skin to the Appearance object using the Add method, and we need to set the last 7 bits in the SelBackColor property to indicates the index of the skin that we want to use. The sample applies the "" to the selected node:
With XMLGrid1 With .VisualAppearance .Add &H22, App.Path + "\selected.ebn" End With .SelForeColor = RGB(0, 0, 0) .SelBackColor = .SelBackColor Or &H22000000 .SelBackColorChild = .BackColor .SelForeColorChild = vbBlack End With
The following C++ sample changes the visual appearance for the selected node:
#include "Appearance.h" m_xmlgrid.GetVisualAppearance().Add( 0x22, COleVariant(_T("D:\\Temp\\EXMLGrid.Help\\selected.ebn")) ); m_xmlgrid.SetSelBackColor( RGB(0,0,255) | 0x22000000 ); m_xmlgrid.SetSelForeColor( 0 ); m_xmlgrid.SetSelBackColorChild(m_xmlgrid.GetBackColor()); m_xmlgrid.SetSelForeColorChild( 0 );
The following VB.NET sample changes the visual appearance for the selected node:
With AxXMLGrid1 With .VisualAppearance .Add(&H22, "D:\Temp\EXMLGrid.Help\selected.ebn") End With .SelForeColor = Color.Black .Template = "SelBackColor = 587137024" .SelBackColorChild = .BackColor .SelForeColorChild = Color.Black End With
where the 587137024 value is the hexa representation of 0x22FF0000
The following C# sample changes the visual appearance for the selected node:
axXMLGrid1.VisualAppearance.Add(0x22, "d:\\temp\\EXMLGrid.Help\\selected.ebn"); axXMLGrid1.Template = "SelBackColor = 587137024"; axXMLGrid1.SelForeColorChild = Color.Black; axXMLGrid1.SelBackColorChild = axXMLGrid1.BackColor;
where the 587137024 value is the hexa representation of 0x22FF0000.
The following VFP sample changes the visual appearance for the selected node:
With thisform.XMLGrid1 With .VisualAppearance .Add(34, "D:\Temp\EXMLGrid.Help\selected.ebn") EndWith .SelForeColor = RGB(0, 0, 0) .SelBackColor = RGB(0,0,255) + 570425344 .SelBackColorChild = .BackColor .SelForeColorChild = RGB(0, 0, 0) EndWith
With XMLGrid1 .VisualAppearance.Add &H34, App.Path + "\aqua.ebn" .SelBackColor = &H34000000 End With
Please notice that the 34 hexa value is arbitrary chosen, it is not a predefined value. Shortly, we have added a skin with the identifier 34, and we specified that the SelBackColor property should use that skin, in order to change the visual appearance for the selected item. Also, please notice that the 34 value is stored in the first significant byte, not in other position. For instance, the following sample doesn't use any skin when displaying the selected item:
With XMLGrid1 .VisualAppearance.Add &H34, App.Path + "\aqua.ebn" .SelBackColor = &H34 End With
This code ( red code ) DOESN'T use any skin, because the 34 value is not stored in the higher byte of the color value. The sample just changes the background color for the selected item to some black color ( RGB(0,0,34 ) ). So, please pay attention when you want to use a skin and when to use a color. Simple, if you are calling &H34000000, you have 34 followed by 6 ( six ) zeros, and that means the first significant byte of the color expression. Now, back to the problem. The next step is how we are creating skins? or EBN files? The Exontrol's exbutton component includes a builder tool that saves skins to EBN files. So, if you want to create new skin files, you need to download and install the exbutton component from our web site. Once that the exbutton component is installed, please follow the steps.
Let's say that we have a BMP file, that we want to stretch on the selected item's background.
You can always open the skin with the builder and change it later, in case you want to change it.
Now, create a new project, and insert the component where you want to use the skin, and add the skin file to the Appearance collection of the object, using blue code, by changing the name of the file or the path where you have selected the skin. Once that you have added the skin file to the Appearance collection, you can change the visual appearance for parts of the controls that supports skinning. Usually the properties that changes the background color for a part of the control supports skinning as well.
